LeechBlock alternative for Chrome: Stillwood vs LeechBlock NG
Updated 14 October 2026
The short answer
Both are free and neither collects your data. LeechBlock NG fits better if you want detailed rules: up to 30 block sets with their own schedules, time limits and a password. Stillwood is quicker to set up and works on the moment you open a site: it pauses, asks why, and offers a way back to work that fits your answer.
What they have in common
Both are free Chrome extensions, and both state that they don’t collect your data. Both can block on a schedule, hold a site behind a countdown before it opens, and keep sites completely closed for a while.
Where LeechBlock NG does more
- You can set up to 30 block sets, each with its own times and days.
- It has time limits, for example 10 minutes in every hour.
- A password or a random access code can protect its options page, so it’s harder to switch off on impulse.
- It runs on Firefox, including Firefox for Android, as well as Chrome.
- Its code is public under the Mozilla Public License 2.0.
Where Stillwood is different
- Setup takes about a minute: pick your sites, pick a schedule and you’re done.
- When you open a site, it asks what’s pulling you there: bored, tired, anxious, don’t know where to start, need it for work, or it just opened itself. Each answer gets a response that fits, like 5 minutes away from the screen when you’re tired.
- On YouTube it hides the home feed, Shorts and recommendations and keeps search working, so you can use YouTube for work without getting pulled in.
- If you keep coming back to a site within an hour, the pause gets longer on its own.
- Every 20 focused minutes grows a ring, and the “What pulled you” list shows your most common reasons over time.
- It speaks English, Spanish, Portuguese, German, Turkish and Russian.

Questions
Is LeechBlock NG available for Chrome?
Yes. It’s in the Chrome Web Store as well as on Firefox Add-ons.
Can I use Stillwood and LeechBlock together?
You can, but if both act on the same site the result gets confusing. It’s simpler to give each one different sites, or to use just one.
Does Stillwood have limits like “10 minutes per hour”?
No. Stillwood lets you open a site for 10 minutes when you choose to, and the pause gets longer if you keep coming back. If you want strict time quotas, LeechBlock NG has them.
